Set the TextAreaCursor?

I am finishing up a "core" IDE that will be released with full BlitzPlus source, for people to make their own IDE's from. The program is really good, but I ran into some limitations of the language. I need to set the cursor and selection length of a textarea. I also need to be able to disable the automatic CTRL+Z undo for the text area. I also need to get and set a string in the clipboard.

If I can get these problems solved, I'll release this useful code and editor.

Thanks.
